SRAM DUB English BSA Bottom Bracket - 68/73mm | MTB Boost
What frame standard does the SRAM DUB English BSA 68/73mm MTB Boost fit?
The SRAM DUB English BSA Bottom Bracket for 68/73mm MTB Boost is a threaded bracket designed for English/BSA-threaded frames with Boost rear spacing — the 148mm rear axle standard that requires a slightly wider bottom bracket shell offset to produce the correct chainline for Boost-spaced drivetrains. Boost MTB frames use either a 68mm or 73mm BSA shell depending on frame construction material, and this bracket accommodates both widths while delivering the chainline offset needed to pair correctly with Boost-width cassettes and cranksets. The oversized DUB spindle seats into sealed cartridge bearings with Gutter Seal Technology at the interface, keeping trail grime and moisture out of the bearing race over extended riding seasons.
Threaded English/BSA installation uses a standard BSA bottom bracket tool — right-hand drive side threading (remember: the drive-side cup threads in counterclockwise on English/BSA), no press equipment required. If your frame is English/BSA at 68mm or 73mm with Boost rear spacing and you are running any SRAM DUB MTB crankset designed for Boost, this is the correct bracket. Do not substitute a non-Boost BSA bracket, as the chainline will be off. Compatible with all current SRAM Eagle DUB MTB cranksets including GX, X01, XX1, GX T-Type, and X0 T-Type in Boost configurations.
